Using the Phillips head screwdriver, tighten the four screws in a diagonal manner (as shown in the diagram). Tighten each screw half of the screw length for A to B and follow by ¼ for C to D. Then tighten A to B until the screw hard stops and repeat for C to D. The screws are designed to compress the springs a predetermined amount.

2.6.6MCH Heatsink Installation

This section may not apply if the MCH heatsink is pre-installed on the board. However, you may want to briefly look over the procedure to verify that the heatsink is properly installed and it has not been damaged in the packaging.

Note: If the Thermal Interface Material (TIM) is scratched, scrape it off and replace with new material. Use a TIM with high thermal conductivity, such as thermal grease or phase change material.
